Engine Performance problem
1991 Pontiac Grand Prix 4 cyl Front Wheel Drive Automatic 150000 miles
When you try to gain speed you can't. WHen you are trying to drive down the road the engine kinda studders and when you floor it it just goes blaaaahhhh and has no power to go. It is firing on all cylinders there is no problems in the exhaust for they are new from engine back. I have changed the coils, coil housing, ingnition control module, plugs, plug boots, sent a top grade fuel injector cleaner through it, changed the fuel pump, fuel filter, and made sure the fule lines were clear. The exhaust is coming out a little blue and smells like gas and is burning through gas like mad. I know it is firing on all cylinders but I have no clue what is wrong.
